The Mount Toondina structure, a small but pronounced vertically fault-bounded inlier of Permian sediments within a flat-lying Mesozoic sequence, is represented by an annular magnetic feature located 45 km south of Oodnadatta. A single gravity profile...

This project has been undertaken to develop fission-track dating expertise for several common minerals, which can subsequently be applied to specific geological or geochronological problems in South Australian regional geological mapping. In...

Exploration for lacustrine evaporites and for detrital heavy minerals on and near the shores of Lake Alexandrina, south of Milang, had previously located minor deposits of garnet sands along a 700 m stretch of beach on the northern shore of Sturt...

The Gawler Craton has, for some time, been known to have potential for kimberlite discoveries. Recently, Orogenic Exploration Pty Ltd found a complete range of kimberlitic indicator minerals, and five small diamonds, on Flinders Island, about 40 km...

An airborne magnetic survey acquired by the grant licensee over the Lameroo district during August 1997 generated a number of shallow-source anomalies which suggested that there was fair potential for discovering buried Tertiary palaeocoastal...

Following a literature review of the mode of occurrence, field relationships, matrix mineralogy and geochemistry of Terowie - type kimberlite intrusions, the lease operator undertook large scale costeaning and bulk sampling of four kimberlites in that...

A suite of Jurassic kimberlite dykes occur near Orroroo, South Australia. They range in thickness from a few millimetres to 30 metres. The intrusions are all extensively altered at surface, but a few of them are petrographically similar, and have...

An 11 km x 23 km area located east of Broken Hill township was chosen for the acquisition of an experimental OARS (Operational Airborne Remote Sensing) and prototype TIPS (Thermal Infrared Profiling System) hyperspectral survey flown during the period...

Exploration conducted primarily for base metals, over an area extending for 5-50 km north of Port Lincoln, has consisted of reconnaissance and detailed stream sediment surveys followed by soil and rock chip sampling, plus limited geological mapping....

After two intensive regional reconnaisance programmes of heavy mineral sampling, backed up by air photointerpretation and drill hole record checks, the licensee has concluded that the tenement areas relinquished have a low prospectivity for diamonds....

Possible Cainozoic garnet-rich heavy mineral sand placer deposits that might have been derived from erosion of Cambrian Kanmantoo Group metasediments were investigated by very shallow auger drilling (11 holes, total 19 m) and beach sand sampling...

Exploration for possible kimberlite pipes in the Mount Arthur - Mount Toodla area, 30 km east-southeast of Oodnadatta, has included preliminary gravity and ground magnetic surveys, stream sediment sampling, and the drilling of a single diamond cored...

Results of reconnaissance geochemical sampling of outcrop and lag gravels of ?Birksgate Complex ferruginous quartzites within the eastern Musgrave Block did not justify further exploration for potential Broken Hill-style exhalative Pb-Zn-Ag deposits.

A single dodecahedral 0.375 mm x 0.3 mm microdiamond and several different kimberlitic indicator minerals were recovered during regional stream sediment and gravel sampling of an area surrounding and extending south-west of Hawker. Follow-up...

Diamonds and base and precious metal exploration undertaken north-east of Port Kenny on western Eyre Peninsula comprised loam sampling for kimberlite indicator minerals, RC drilling (7 vertical holes, total 470 m), plus bedrock petrological, heavy...

Ground magnetic surveys were carried out over seven interpreted aeromagnetic anomalies located north-west of Port Augusta. Those with interpreted source depths that were shallow enough to be reached by RC drilling (6 holes, total 570 m) were found to...
